Abstract :
A description of a mixer mount with integrated image filter and l.o. injection filter is presented. The image filter is a high-pass filter using the cut-off properties of a circular waveguide section. The l.o. power is coupled selectively via a TE111-mode filter into the mixer waveguide. The i.f. matching transformer has been designed by a microstrip technique.
